无缝线路检测方法浅谈

摘要

In recent years,seamless tracks have become the common trend and their testing has been the focus of attention.The paper briefly introduces the significance of the testing of seamless tracks while in operation,the testing methods and principles at a fixed rail temperature,and taking as an example the setting of the displacement observation piles of the Beijing-Tianjin intercity railway and the Beijing-Shanghai high-speed railway,introduces the application of the piles in high-speed railways and explains the computation of fixed rail temperature with the help of the piles with examples.%近年来,无缝线路应用已成普遍趋势,无缝线路检测一直是被关注的问题。简要介绍了营运期间无缝线路检测意义、目前无缝线路锁定轨温检测方法原理。以京津城际及京沪高铁位移观测桩设置方法为例,介绍了位移观测桩法在高速铁路中的具体应用,举例说明了位移观测桩法计算实际锁定轨温。
